ఈ-మెయిల్: కూర్పుల మధ్య తేడాలు

కుడి ప్రక్క చుపిన పటంలో అలీస్ మెయిల్ యుజర్ ఏజెంట్ ([[E-mail client|mail user agent]] (MUA)). ఉపయొగించి మెసెజ్ కంపొజ్ చెసెటప్పుడు జరిగె పరిణమాన్ని చూపించటమైనది. అలీస్([[Placeholder names in cryptography|Alice]] ) తన ఇ-మెయిల్ అడ్రస్ ([[e-mail address]]) టైప్ చేసి “send” బటన్ నోక్కినప్పుడు ఈ క్రిందవి జరుగుతాయి.

# Her MUA formats the message in e-mail format and uses the [[Simple Mail Transfer Protocol]] (SMTP) to send the message to the local [[mail transfer agent]] (MTA), in this case <tt>smtp.a.org</tt>, run by Alice's [[Internet Service Provider]] (ISP).

# The MTA looks at the destination address provided in the SMTP protocol (not from the message header), in this case <tt>bob@b.org</tt>. An Internet e-mail address is a string of the form <tt>localpart@exampledomain</tt>. The part before the @ sign is the '''local part''' of the address, often the [[username]] of the recipient, and the part after the @ sign is a [[domain name]] or a [[fully qualified domain name]]. The MTA resolves a domain name to determine the fully qualified domain name of the [[mail exchange server]] in the [[Domain Name System]].

Messages are exchanged between hosts using the [[SMTP|Simple Mail Transfer Protocol]] with software programs called [[mail transfer agent]]s. Users can retrieve their messages from servers using standard protocols such as [[Post Office Protocol|POP]] or [[IMAP]], or, as is more likely in a large [[corporation|corporate]] environment, with a [[Proprietary software|proprietary]] protocol specific to [[Lotus Notes]] or [[Microsoft Exchange Server]]s. [[Webmail]] interfaces allow users to access their mail with any standard [[web browser]], from any computer, rather than relying on an e-mail client.
